Mapeband corner 90° and 270° corner pieces are pre-formed elastic components used to reinforce waterproofing at internal and external corners where movement commonly causes leaks. They provide consistent corner detailing without cutting or folding flat tape on site.
Designed to integrate with compatible liquid-applied waterproofing systems, these corner pieces remain flexible after installation and can be tiled or coated over. Suitable for wet areas, balconies, terraces, and other moisture-exposed junctions.
